Abstract

The invention discloses a method for canceling a node data relationship in a graphic database online transaction. The method comprises the following steps: receiving a transaction canceling operation command transmitted by a client, wherein the operation command comprises a transaction number and a node data relationship to be canceled; searching for the corresponding transaction according to the transaction umber; and opening a transaction processing mark when the transaction is effective and operation data in the transaction is not locked by other transactions, and canceling the node data relationship to be canceled in the transaction. The node data relationship canceling method and system provided by the embodiment of the invention can perform canceling and other corresponding operations on the node data relationship to be canceled in each stage of the transaction operation process on the premise that the transaction is effective and the operation data in the transaction is not locked by other transactions.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method and system for canceling node data relationships in graph database online transactions. Background technique [0002] A graph database is a data set that uses a computer to store the basic elements of points, lines, and graphs in a certain data combination, and describes the graphs in maps and other types of planes as basic elements such as points, lines, and planes. These graphical elements are data collections established according to a certain data structure (usually a topological data structure). [0003] Typically in database systems, a transaction is a discrete unit of work; for example, a database transaction could be a write operation that modifies a user's account balance or inventory item. The operation object of a transaction is node data; in a graph database, the logical unit of data storage is a node, and nodes are connected to each other through at...
